[LARTC] src routing and fwmark

[the sew]

Hi,

I've got 2 lines from two diffrent ISP's, one is a leased line and another a
DSL line,

I route certain  ips over the DSL line for faster access and would like
email to go over the leased line as it has a static ip and is our sending
mailserver ip

I would like to send mail to the same ips that is routed over DSL via the
leased line, otherwise my server gets blacklisted with the DSL ip

my routing table

164.148.0.0/14 dev ppp0  scope link
196.0.0.0/8 dev ppp0  scope link
default via 196.34.17.1 dev eth0  proto zebra equalize

If I send mail to a ip on 196.0.0.0/8 on port 25 it must go via 196.34.17.1

my other routing tables:
200     dmz
201     ppp

ip rule add fwmark 25 table dmz
ip route add default via 196.34.17.1 table dmz

iptables -t mangle -A OUTPUT -p tcp --dport 25 -j MARk --set-mark 25


I can see the packets get matched but still goes via ppp0, is there anyway
to overcome this?

Thanks

Sew
